The Museum of African Art and Culture in Portland is closing its downtown location and converting its collection to a digital format.

The museum will host a fundraising event at 5:30 p.m. Thursday at its current location at 13 Brown St. It will be the final event at the location, museum founder and Executive Director Oscar Mokeme said in an email to supporters.

“The museum is transitioning into a digital program and possibly collaborating with the Portsmouth (N.H.) African Burial Ground to expand the museum there. While we are giving up our location at 13 Brown Street we are by no means closing,” he wrote. “Our outreach and education programs will remain the same, as will our mission statement and goals.”

The museum opened Aug. 8, 1998. It has more than 1,500 pieces in its collection, including masks, figures, textiles and other objects. The oldest mask dates to 1600 A.D.

Thursday’s event will include an auction of local art and raffles, as well as entertainment.
